Create a k-ary tree graph, where almost all vertices other than the leaves have the same number of children.
Usage
make_tree(n, children = 2, mode = c("out", "in", "undirected"))
tree(...)
Arguments
- n
Number of vertices.
- children
Integer scalar, the number of children of a vertex (except for leafs)
- mode
Defines the direction of the edges.
out
indicates that the edges point from the parent to the children,in
indicates that they point from the children to their parents, whileundirected
creates an undirected graph.- ...
